Applicationiiled SeptemberA, 1924.1 Serial No.735561 05 5 This inventionrelates to a class of combination socket wrenchsuch .aS maybe ordinarilyneeded about automobile motors. for

manipulating bolts and nuts on the same.,.

at particular object otmy invention is to provide a combination socketwrench o t the characterherein described and cla med and which in itsmerited "design is adapted to 7 *-provide easy access to several of themore diificult recesses aboutthe morerecent models o't'l ord automobilesand more part-ion larly such places. asf the retaining bolts forthecarbureter and the starter generator.

The desired object of my invention is attained by the socket wrench forFord automobiles, described in the annexed specifica-' tions, recited inthe claim and illustrated in the accompanying drawings in which likereference numerals indicate the same structural parts in the severalfigures. I

In the drawings Fig. 1 1s a perspective of the wrench of my inventionFig. 2 1s a side elevation of the wrench of my inVen-' tion. Fig. 3 is atop view of the wrench of my invention. 1 1g. 4 IS a sketch showing howthe wrench may be successfully used in close places about a car motorthat are i suits may be obtained with this my invention it will beobserved that the.

The preferred embodiment of my invention is illustrated in the/"severalfigures above mentioned and the desired means of operating the same willbe clearly set forth in the instructions which follow.

Referring now to the structural detail of rsockets on opposite ends ofthe wrench for the sake of convenience should be of unlike size and asize in each case which will be the. most practical for the greatestnumber I of principles of operation.

,bolts aiiat'eaajg at likely to. 1,; lanai wrench r ordinaryz design.

among automobile mechanics to find certain Pa s f moto j n s h ape itonj i nut desired to be respect to the" bolt worked on that it iswithlt-hegreatest ditliculty thatItheunechanic is able to secure afirmwrenchgrip onthe head ,of-abolt ornut L tion.

about thelmotor ofa well known automobile; and more particularly suchbolts and nuts arenot easily accessible becauseof some mechanic-alobstruction that may stand in the; .4 way of sec a t f o y ip w t It 3is matter of co nmoneiperience Vi away that where the'hand powerisapplied for'normallyturningthe bolt that the direc-, tion otmoveinentand theyrelative position o t-{the hand. infturning the. wrench has hada tendency to cause the wrench socket to slip off ot the bolt head evenin spite of efforts that have been commonly made in such cases I to.hold the wrenchdown securely on the turning the wrench.

bolt head by means of the hand not-fused in It is tobe further observedin this respect that when the mechanic is workingin such" close places;and manipulating a wrench with one" hand he can usually get betterresults by havingzone hand free with which to balance hispoiseinsteadof'having to use 7 his free hand for exerting pressure down on,the wrench to keep ittroinslippmg off the" bolt head.

The novel design of the I socket wrench of my invention will preventthedifiiculties above mentioned for the reason that it'is designed onscientifically correct mechanical I Referring to the detailsofconstruction, a' method of manufacture of-a wrench of this characterwould beto form the knobs 6 and'7and5sockets land 2"at correspondingends of a straight handle after which handle i 3 isbent. near the endsto formthe'wrenchnecks 4 and 5 respectively parallel Witheach other andat right angles to the handle 37 and on the same side of the straightbody portion. 1 7

It will now be noted thatwhen thewrench is thus formed and ready for usethemeehanicmay use the wrench with great satisfaction in diflicultsituations about the type of car for which it is best adapted;

For instance referring to Fig. 4L if the mechanic desires to tighten acap screw 8 with this wrench in a difiicultvplace about the motor -9 hemay for example place wrench socket 2 over the head of cap screw 8 wherewrench neckd and handle 3 make integral connection with neck 5 and knob6"at the opposite end of the wrench which are jointly used normally as ahand grip for the mechanic when turning the cap screw 8 in whichflcasethe knob 6 is adapted to normally fit snugly into the mechanics hand inmanipulating the wrench.

'It will be seen-from the foregoing description of the wrench of myinvention that when the hand power of the mechanic is appliedto knobz6moving the wrench in an are about agcentral axis located at the 1011-gitudinal. center of cap screw 8-Vthat the exert-ed' hand pressure beingin the same pivotal plane with the said'cap screw head will properlypoise the wrench socket over the Cap screw head an'dthus havea'tendency,

to hold the wrench on the cap screw without the necessity of exertingextra pressure on the wrench in order to hold it downon the cap screw, athing which is Very difficult to do in places that are not easilyaccessible about the car motor;

'It will be observed that whena mechanic is working in close placesunder or around a Ford car motor and-is using a wrench he usually needsone hand on the wrench and the other for stabilizing his poise and thismodels but it will be seen that the same merits will hold good wheresquare sockets are usedor square headed bolts, nuts and studs. I r

Havingthus described the nature of my invention'what I claim as new anduseful and desire to secure by Letters Patent is:

A wrench comprising a straight body portion having integral arms carriedby the ends of said body portion at substantially right angles, theretoin parallel relation to each other on the same side of said straightbody member and in the same plane as the body portion and provided withnut receiving recesses in their ends, said arms of equal length forminghandle members when either arm is in engagementwithv a nut, whereby aleverage action maybe applied to the nut in the plane of the nut; r v

In witness whereof, I hereunto set my hand and seal, this 21st day ofAugust A,
